| * ath9k: make PA linearization optional, disabled by default and fix checksFelix Fietkau2012-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | Some checks for PA linearization support checked ATH9K_HW_CAP_PAPRD and some used the EEPROM ops, leading to issues in tx power handling, since those two can be out of sync. Disable the feature by default, since it has been reported that it can cause damage to the rx path under some circumstances. It can now be enabled for testing via debugfs.

| * simple_open: automatically convert to simple_open()Stephen Boyd2012-04-05

This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* | ath9k: Add more recv stats.Ben Greear2012-04-11
| | | | | | | | | | | | | | | | | | | | | | | | This adds counters in various places that can drop packets on rx without otherwise incrementing a counter.

* ath9k: unify edma and non-edma tx code, improve tx fifo handlingFelix Fietkau2011-06-01
| | | | | | | | | | | | | | | | | | | | | | | | EDMA based chips (AR9380+) have 8 Tx FIFO slots, which are used to fix the tx queue start/stop race conditions which have to be worked around for earlier chips by keeping the last descriptor in the queue. The current code stores all frames that do not fit onto the 8 FIFO slots in a separate list. Whenever a FIFO slot is freed up, the next frame (or A-MPDU) from the pending queue gets moved to that slot. This process is not only inefficient, but also unnecessary. The code can be improved visibly by keeping the pending queue fully linked, and moving the contents of the entire queue to a FIFO slot as it becomes available. This patch makes the necessary changes for that and also merges some code that was duplicated for EDMA vs non-EDMA. It changes txq->axq_link to point to the last descriptor instead of the link pointer, so that ath9k_hw_set_desc_link can be used, which works on all chips. With this patch, a small performance increase for non-aggregated traffic was observed on AR9380 based embedded hardware. Signed-off-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: John W.
